Area forecast discussion, Jul 17, 8:56 PM EDT, 4 minutes before
AREA FORECAST DISCUSSION National Weather Service Wakefield VA 856 PM EDT Sat Jul 17 2021 .SYNOPSIS... A weak cold front slowly moves through the local area Sunday morning then settles near the Virginia North Carolina border late Sunday into Monday bringing chances of mainly afternoon and evening showers and thunderstorms. Drier conditions arrive by Tuesday. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... As of 850 PM EDT Saturday... Sct tstms continue to move east along a leading sfc trof this eve with the activity now east of RIC, apprchg SBY/PHF. Although some wind gusts to arnd 40 mph are psbl in the leading storms, think svr threat has just abt ended given loss of daytime heating. Any threat now will be lclly hvy downpours but the storms are moving to the east so no sgnfcnt flooding expected. Models show the activity weakening then dissipating by or shortly after 06Z, so will keep chc/low end likely PoPs until then. Expect a lull in the activity later tonite/Sun morning before anthr round of convection dvlps across srn VA/nrn NC along the actual cold front Sun aftrn. Still muggy overnite despite the temp drop after the storms. Lows 70-75 except for some upr 70s across the se. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/... As of 355 PM EDT Saturday... The aforementioned cold front will approach from the NW Sunday morning and will be weakening at the same time. By afternoon, the boundary is expected to settle into central VA. Showers/tstms are expected to develop Sunday afternoon and linger into the evening, especially across southern VA and NE NC. Forecast PoPs are mainly 30-60% as there remains some uncertainty with respect to convective coverage. Brief heavy rain is possible with any storms, but the risk for flooding is low. Showers and a few embedded tstms could linger overnight, but coverage and intensity should wane during the overnight hours. Highs Sunday range from the mid 80s to around 90F, with lows Sunday night in the mid 60s to low 70s. The front lingers over the area Monday, before pushing farther SE Monday night into Tuesday as weak high pressure builds in from the NW. PoPs Monday range from 20-30% N to 60-70% S. Again, heavy rain will accompany showers/tstms, but there is not enough confidence with regard to coverage for a widespread flooding risk. A drier airmass arrives from the NW Monday night and spreads across the area Tuesday. Highs Monday range from around 80F S with clouds and occasional showers/tstms, to the mid 80s N. Lows Monday night range from the mid 60s to around 70F. Highs Tuesday range from the mid to upper 80s. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... As of 355 PM EDT Saturday... A cold front approaches from the north Wednesday into Wednesday night, before weak high pressure builds in from the north Thursday. There is only a minimal chc of showers/tstms with this front Wednesday afternoon and evening. Another weak cold front moves through Friday and Friday night with a another chc of showers/tstms. Weak high pressure builds into the area Saturday. Highs will be seasonal and range from the upper 80s to around 90F Wednesday to Saturday. Lows will range from the mid 60s to around 70F Tuesday through Friday nights. && .AVIATION /01Z SUNDAY THROUGH THURSDAY/... As of 850 PM EDT Saturday... Sct tstms cont this eve along a leading sfc trof across VA/MD with addntl convection across the mts ahead of a cold front that will cross the area Sun. Thus, have kept VCTS with a tempo for storms at RIC/SBY with only VCTS at ORF/PHF and kept it dry at ECG for the next few hrs. Latest guid shows the pcpn weakening then dissipating by or shortly after 06Z. Otw, VFR outside on convection with lcl IFR VSBYS in lclly hvy rainfall. Should see a lull in the activity cont into Sun morning with more convection dvlpng Sun aftrn ahead and along the cold front. Expect most activity across srn VA/nrn NC. S-SW winds aob 10 kts outside of tstms. OUTLOOK... Flight restrictions cont into Sun night and Mon across the south as the cold front lingers near the VA/NC border. Drier conditions arrive by midweek as high pressure builds into the area. && .MARINE... As of 130 PM EDT Saturday... A slow moving cold front will approach the area from the NW late tonight, then slowly move across the waters late Sunday through Mon morning. SW winds will average around 15kt for the Bay/Rivers/Currituck Sound through tonight and 15-20 kt for the coastal waters. Waves 1-3 ft...seas 2-4 ft...maybe 5 ft out at or past 20 nm. Lowering SSW winds on Sun, which should become WSW or W for a while across the northern waters Sunday evening/night as the front washes out. With the front weakening/dissipating on Monday, expect generally SSW winds aob 10 kt. Waves 1-2 ft; seas 2-3 ft.
